“…Involvement of MCP joints in OA without node formation is less apparent but is evidenced with different methods (21). JSW of MCP and PIP joints is normal in early RA (18), but is reduced in the case of coexisting OA (22).…”

“…Many authors have studied the effect of OA on hand function and have had contradictory results [3,5,7,14,20,27]. Baron et al [3] reported no correlation between hand strength and the degree of radiologic hand OA.…”

“…If at least one joint of that digit-joint group had radiographic OA, that group had OA. To quantify the overall radiographic severity of hand OA in each digit-joint group, we summed the Kellgren and Lawrence grades of three joints (DIP, PIP, MCP) in each of the four fingers, and of the IP, MCP, and CMC joints in the thumb [5].…”

Background Interpreting the impact of hand osteoarthritis (OA) on hand function is complicated owing to the multiple digits and joints in the hand. Questions/purpose We determined the impact of digitrelated radiographic OA on hand function in patients 65 years or older.Methods We evaluated hand radiographs in 196 men and 182 women older than 65 years without shoulder or elbow pain who participated in the Korean Longitudinal Study on Health and Aging. Using the Kellgren and Lawrence criteria, we graded the 15 joints in each hand from 0 to 4 for OA, and evaluated hand function by measuring DASH scores and grip and pinch strength of dominant hands. We performed multiple linear regression analyses to evaluate associations between hand functions and the sum of Kellgren and Lawrence grade of each digit. Results The sums of Kellgren and Lawrence grades for thumbs and middle fingers were independently associated with grip strength, and the sums of the Kellgren and Lawrence grades for thumbs and index fingers were independently associated with pinch strength after controlling for age and sex. DASH scores were independently associated with OA of the thumb, or index or middle finger, but not with OA of the ring or small finger. Conclusions This study revealed cumulative effects of joint involvement and Kellgren and Lawrence grades of thumb and middle finger OA on grip strength, and thumb and index finger OA on pinch strength. Furthermore, OA of either of three radial digits was associated with more severe upper extremity disabilities.

“…Studies support an association of advanced age, female sex, family history, and increased BMI with CMC OA [2,6,16,30]. Pinching tasks are especially uncomfortable for patients with early OA, and patients with CMC and distal interphalangeal arthritis have been shown to have lower pinch and grip strength [1,5,8,17,24]. The extent to which this weakness during functional tasks informs the diagnosis of early CMC OA has been preliminary but not rigorously quantified in the literature [15,22].…”

Background The thumb carpometacarpal (CMC) joint orchestrates pinch in its various positions, and thumb CMC osteoarthritis (OA) is a major source of orthopaedic morbidity. Self-reported pain, weakness, and physical examination may not correspond to radiographic findings when diagnosing early thumb CMC OA. Weakness is a prominent feature of the disease, but little evidence exists to quantify self-reported loss of strength with time, or to compare weakness with that of a nonarthritic population during early disease. Questions/purposes We asked: (1) Is pinch strength in subjects with early thumb CMC OA less than that in asymptomatic control subjects; and (2) weakness in which pinch position (key, tripod, or tip pinch) has the strongest association with early OA diagnosis? Methods For this case-control study, we recruited 23 subjects who were asymptomatic and 91 with early OA for comprehensive history, physical examination, strength measurements, pain surveys, and radiographic evaluation. We used multivariate logistic regression to quantify the association between declining pinch strength and early OA diagnosis after controlling for age, sex, and BMI. This analysis was performed for three different pinch positions (key, tripod, and tip pinch) to evaluate which measurement was most closely associated with diagnosis. Results Pinch strength was less in patients with early thumb CMC OA. Key pinch had the most robust association with OA diagnosis, in which a 20% decrease in key pinch strength from the control subjects' baseline was associated with a 10% increase in the OA diagnosis (95% CI, 3%-16%; p = 0.004). This had a stronger association with OA diagnosis than tip pinch, in which a 20% decrease in strength was associated with a 6% increase in early CMC OA (95% CI, 1.0%-11%; p = 0.031). Tripod pinch also was associated to a lesser extent; a 20% reduction in tripod pinch led to a 5% increase in OA (95% CI, 1.3%-9%; p = 0.048). Conclusions Decreasing pinch strength, especially key pinch, is associated with early CMC arthritis before the development of extensive radiographic disease.
